Ubuntu Security Notice (C) 2010-2013 Canonical, Inc. / NASL script (C) 2010-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

It was discovered that OpenSSL incorrectly handled return codes from
the bn_wexpand function calls. A remote attacker could trigger this
flaw in services that used SSL to cause a denial of service or
possibly execute arbitrary code with application privileges. This
issue only affected Ubuntu 6.06 LTS, 8.04 LTS, 9.04 and 9.10.
(CVE-2009-3245)

It was discovered that OpenSSL incorrectly handled certain private
keys with an invalid prime. A remote attacker could trigger this flaw
in services that used SSL to cause a denial of service or possibly
execute arbitrary code with application privileges. The default
compiler options for affected releases should reduce the vulnerability
to a denial of service. (CVE-2010-2939).

Solution :

Update the affected packages.

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 7.8
(CVSS2#E:POC/RL:OF/RC:ND)
